This is my 1st post.
I recently bought a new 318 (e46), and i'm having problems with the 6 cd changer in the boot. The head unit is factory fitted and seems to be working ok.
When i start the car 1st time, the CD changer isnt recognised by the hed unit, however if i switch the ignision to the off point, leave it for 5 seconds then on again the head unit displays 'Reg Off', and the CD changer can then be seen.
Once this is done the system works fine and cd's are played and changed as normal, until i switch the car off and lock the car, then i have to do it again.
Any ideas would be appreciated.
